Detailed Description

rgbdSensor_nws_ros: A Network grabber for kinect-like devices. This device will produce two streams of data through different ports, one for the color frame and the other one for depth image following Framegrabber and IDepthSensor interfaces specification respectively. See they documentation for more details about each interface.

Description of input parameters

This device is paired with its client called RgbdSensor_nws_ros to receive the data streams.

Parameters required by this device are:

Parameter name	SubParameter	Type	Units	Default Value	Required	Description	Notes
period	-	double	s	0.03	No	refresh period of the broadcasted values in s	default 0.03s
forceInfoSync	-	string	bool	-	no	set 'true' to force the timestamp on the camera_info message to match the image one	-
color_topic_name	-	string	-	-	Yes	the color topic	recommended value /camera/color/image_rect_color
depth_topic_name	-	string	-	-	Yes	the depth topic	recommended value /camera/depth/image_rect
color_frame_id	-	string	-	-	Yes	set the name of the reference frame for the color camera
depth_frame_id	-	string	-	-	Yes	set the name of the reference frame for the depth camera
node_name	-	string	-	-	Yes	set the name for ROS node	must start with a leading '/'

ROS message type used is sensor_msgs/Image.msg ( http://docs.ros.org/api/sensor_msgs/html/msg/Image.html) Some example of configuration files:

Member Function Documentation

◆ attach()

bool RgbdSensor_nws_ros::attach ( yarp::dev::PolyDriver * poly )

overridevirtual

Specify which sensor this thread has to read from.

Implements yarp::dev::IWrapper.

Definition at line 191 of file RgbdSensor_nws_ros.cpp.

◆ close()

bool RgbdSensor_nws_ros::close ( )

overridevirtual

Close the DeviceDriver.

Returns: true/false on success/failure.

Reimplemented from yarp::dev::DeviceDriver.

◆ detach()

bool RgbdSensor_nws_ros::detach ( )

overridevirtual

WrapperSingle interface.

◆ open()

bool RgbdSensor_nws_ros::open ( yarp::os::Searchable & params )

overridevirtual

Device driver interface.

RgbdSensor_nws_ros & RgbdSensor_nws_ros::operator= ( RgbdSensor_nws_ros && )

delete

◆ run()

void RgbdSensor_nws_ros::run ( )

overridevirtual

Loop function.

This is the thread itself. The thread calls the run() function every <period> ms. At the end of each run, the thread will sleep the amounth of time required, taking into account the time spent inside the loop function. Example: requested period is 10ms, the run() function take 3ms to be executed, the thread will sleep for 7ms.

Note: after each run is completed, the thread will call a yield() in order to facilitate other threads to run.

Implements yarp::os::PeriodicThread.

Definition at line 417 of file RgbdSensor_nws_ros.cpp.

◆ threadInit()

bool RgbdSensor_nws_ros::threadInit ( )

overridevirtual

Initialization method.

The thread executes this function when it starts and before "run". This is a good place to perform initialization tasks that need to be done by the thread itself (device drivers initialization, memory allocation etc). If the function returns false the thread quits and never calls "run". The return value of threadInit() is notified to the class and passed as a parameter to afterStart(). Note that afterStart() is called by the same thread that is executing the "start" method.

Reimplemented from yarp::os::PeriodicThread.

Definition at line 216 of file RgbdSensor_nws_ros.cpp.

◆ threadRelease()

void RgbdSensor_nws_ros::threadRelease ( )

overridevirtual

Release method.

The thread executes this function once when it exits, after the last "run". This is a good place to release resources that were initialized in threadInit() (release memory, and device driver resources).

Reimplemented from yarp::os::PeriodicThread.
